From 220d6c860e0c7853aea6509ea2b5a44463c9af8b Mon Sep 17 00:00:00 2001
From: Maxime Ripard <maxime.ripard@free-electrons.com>
Date: Sat, 31 Aug 2013 23:07:24 +0200
Subject: [PATCH] ARM: sun7i: Enable the I2C controllers
The Allwinner A20 shares the same I2C controller than the one that could
be found on earlier SoCs from Allwinner. There is only a few more of
these controllers. Add all of them in the DTSI.
